The member23 comprises a pair of oppositely disposed,` rearwardly extending,depending, rearwardly inclined arms 24 formed with flanges 25 at theirupper ends which are anchored to the lower face of portion 8. The arms24 merge at their lower ends into the forward end of a base piece 26provided with an opening 21. The base piece 26 is slightly inclined fromfront to rear. Arrangedv below and secured to the lower face of portioni6 is a depending forwardly extending supporting member 23 for a`purpose to be referred to. The member 428 comprises a curved head 2-3anchored to the lower face of portion I6, a depending vertical shank 36of segmented contour and a forwardly extending base piece 3| slightlyinclining upwardly from end of shank 36. merges into the rear end ofbase piece 3|. latter is formed with lan opening 32.

The convertible skate structure includes spring controlled revoluble'front and rear hangers 33, 34 respectively for the front and rear axles35, 3G for the front and rear wheels 31, 38 respectively.

The

'Ihe hangers 33, 34 are substantially of like form but oppositelydisposed.

The hanger 33 comprises a head39 formed of a rectangular forward part 46and a tapered rear part 4|. The part 46 inclines upwardly from rear tofront. The hanger`34 comprises a head 42 formed of a rectangular rearpart 43 and a tapered forward part 44.- The part 43 inclines upwardlyfrom rear to front. The parts 4I and 44 are disposed horizontally, arealigned and extend towards eachother. The parts 46, 43 are positioned onthe base pieces 26, 3| respectively and are formed with openings 45, 46respectively which align and are of greater diam` eter than the openings21, 32 respectively. The

parts 46, 43, each, merge into a pair of oppositely disposed outwardlydirected inclined arms 41 merging at their lower ends into verticallydisposed apertured 4supports 48. The supports 48 carried by the arms 41which extend from. the part 40, have the front axle extend therethrough.The supports 48 carried by the arms 31 which extend from the part 43have the rear axle 36 `extend therethrough. The parts 4I, 44 areprovided with openings 49, 56 respectively. The part 44 is formed with apair of openings 5I, only one shown.

The hangers 33, 34 are supported on the base pieces 26, 3| of themembers 23, 28. The base pieces 26, 3| are connected by the upstandinginclined coupling bolts 52, 53 respectively to the portions 8, I6respectively of body part 1. The

bolts incline rearwardly from their lower to their upper ends. Theinclination of bolt 52 is greater than that of bolt 53. The bolts 52, 53are of like formand each includes an upper circular part 54 providedadjacent its upper end with an annular peripheral iiange 55 and'havingits upper end upset, as at 56. Each bolt includes a peripherallythreaded reduced lower part 51 integral with and depending from. thelower end of part 56. 'At the junction of the parts 54, 51 a peripheralshoulder 58 is formed.

The parts 54 of the bolts 52, 53 extend through the openings I1, I6respectively in the parts I5, I6 respectively of body part 1. The upsetupper ends 56 of the bolts 52, 53 bear against respectively the upperfaces of the parts I5, I6 or body part 1. The flanges 55 of the bolts52,' 53 abut the lower faces of theparts I 5, I 6 respectively skate isused. Arranged on the parts46, 43 respectively of the hangers 33, 34respectively, are ianged collarsv 6|, 62 respectively whichen'compassthe lbolts52, 53 respectively. The spring 59 is interposed betweencollar 6I and the'part I5 of portion 8- of body part 1. The spring 59seats onthe ange of collar 6|` and encompasses the part 54' of bolt 52.The spring 6l] is interposed between collar 62 andV the'part I6 oftheportion I6 of body part'l. 'The spring 59 seats on the flangev of collar62 and encompasses the part 54 `of bolt 53. The parts 40, 43, andcollars 6I, `62 are capable of sliding vertically on the bolts. Theselatter are fixed relativelyto the said base pieces 26,3I and the saidparts I5, I6

by a pair of superimposed nuts 63 secured on the may be termedcontrollers for the oscillation or a revolving of the. hangers. Whenelements 66, 61 are employed the structure is for-street skating and thehangers are 'held stationary. When elements 66, 68 are employed thestructure is for rinkskating land with the forward hanger capableofbeing oscillated and the rear hanger held from` oscillation.` Whenelement 68 is solely employed, the structure is for fancy skating andboth hangers are capable of oscillating. When elements 66, 61 orelements 66, 68 are employed they couple the hangers together andv alsocouple them with body part 1. When element 68 is solely employed itcouples the hangers together but it does not couple them with the bodypor- Ition. When elements 66, 68 are employed the l front wheels oftheskate may turn to the right or left but the rear wheels are held inaligned relation with body part 1. When it is desired to permit of thefront or rear wheels turning to the left or to the right the element 68is solely employed. When it is desired to keep the front and rear wheelsheld in aligned relation with body part 1, the elements 66, 61 areemployed.

' The element 66 isy of rectangular contour in plan and consists of aplate 69 formed of an upper, forward, horizontally disposed end terminalportion 16 provided with an opening 1I, a lower, horizontally disposed,rear end terminal portion 12 formed with a pair of openings 13 forregistry with openings 5I, and an intermediate portion-"14 whichinclines downwardly 'from portion 16 to portion 13. When element 66 isemployed the portion 16 thereof is detachably secured to the body-part`1 by bolt 64 and nut 65 (Figures l and 2*),

and the portion 14 mounted upon and detachably `2'5 securedto the part4dr-fof hanger i341by the hold.-

fastV means 15. extending through the aligning openings\5`|,13.

The element' 61 is of rectangular contour in planand consists of avplate1.6 provided in proximityto the vrear endwith a pair of openingsll forregistry with the openings 5| when element 81: is employed; The elementplate 1.6L between its `transverse medianand forwardend is provided onits lengthwise median with a slot 11e. When elementA B1 'is employed inconnection with element '88,, the rear end portion ofy element 61 isvpositionedagainst the lower face of part M of hanger 34 and isdetachably secured'l to the latter by the holdfast means 15. The forwardend terminal portion. of yelement E1'is positioned against the lowerface of the part 4| of hangerl 33 and is detachably and adjustablysecured to the letter by a headed bolt 18 and a nut 19 coacting with theslot 11 and opening 4.9.

The element 68 is in the form of a coiled spring 88 provided at .itsends withv the hooks 8|, 82.

When element 8,8 is employed with or without element 86, the hook 8| isdetachably connected to hanger 33 by passing such hook through open-king 49, and thehook 82 is detachably connected to hanger 34 by passingit through openingvll. Element 88 may have link portions for shorteningor lengthening.

Each axle will be of like form and will have mounted thereon a tubularspacer 84 arranged between the axle supports 48 of .a hanger.y The ,axlewill extend in opposite directions outwardly with respect to thesupports 4B and its extended portions are peripherally threaded. A pairof spaced oppositely disposed aligned flanged collars 85, 88 will bemounted on each extended portion of an axle. Each wheel will consist ofa pair of spaced parallel annularside members 85,81 merging into a pairof oppositely disposed inwardly extending hub sections 88, 89respectively seated on vbearingballs 98 mounted on the collars 85, 86.

The hubsections oppose in spaced relation the flanges of said collars.The side members 86, 81

are connected together by spaced bolts 9| carrying securing nuts 92.Spaces 93 are mounted on the bolts 9| and arranged ,inwardly'of theouter edges of the side. Each wheel includes a tire formed of anysuitable material such as wood or rubber.`

The tire is `indicated at 94 and consists of an annular body 95lrabbeted on each of its sides to form a reduced portion 96 and annularshoulders 91. The reduced portion 96 extends inwardly between the sidesand the shoulders 91 bear l The tire is againstthe outer edges of thesides. disposed in extended relation with respect to the sides of thewheel. A wheel structure is confined on an axle by a clamping unit 98coacting with collar 86, a support 48 and a threaded extended portion ofan axle. y

The hub sections 88 and 89 above mentioned form a combined tire flangeand ball race.
